I'm using Wicket 1.3.2 and I got this weird exception.
-- source code
WebMarkupContainer result = new WebMarkupContainer("result");
result.add(new AjaxSelfUpdatingTimerBehavior(Duration.seconds(5)));
ListView view = new ListView("connections", new PropertyModel(this,
"connections")){...};
result.add(view);
add(result);
-- exception
